The exemplary embodiments herein provide a method for environmental adaptation of electronic display characteristics, comprising the steps of determining the sunset and sunrise times for the day and determining whether the present time is between sunrise and sunset or between sunset and sunrise. An exemplary method would then proceed by selecting a gamma for the display based on whether the present time is between sunrise and sunset or between sunset and sunrise, and driving the display at the selected gamma. The gamma can further be selected based on Artificial Ambient Light Sensor (AAS) data, which can be calculated during sunrise and sunset transition times.

Method for environmental adaptation of display characteristics based on location

The exemplary embodiments herein provide an electronic display with a display controller in electrical connection with the electronic display and adapted to direct the electronic display to operate per nighttime instructions if the present time is between sunrise and sunset, without accepting any input from an ambient light sensor, and direct the electronic display to operate per daytime instructions if the present time is between sunset and sunrise, without accepting any input from an ambient light sensor. The nighttime instructions may include a first setting for gamma while the daytime instructions may include a second setting for gamma. Sunrise and sunset transition periods can be calculated using Artificial Ambient Sensor Data (AAS), with further settings for gamma chosen based on the AAS data.

Electronic display with environmental adaptation of display characteristics based on location

The exemplary embodiments herein provide an electronic display assembly having a liquid crystal display, a backlight placed behind the liquid crystal display, one or more power modules in electrical connection with the backlight, and a microprocessor in electrical connection with the power module(s). Said microprocessor is adapted to determine the sunset and sunrise times for each day and determine whether the present time is between sunrise and sunset or between sunset and sunrise. The microprocessor is further adapted to direct the power module(s) to drive the backlight at a daytime level if the present time is between sunrise and sunset, and direct the power module(s) to drive the backlight at a nighttime level if the present time is between sunset and sunrise.

Display brightness control based on location data

The exemplary embodiments herein provide a method for controlling the luminance of an electronic display, including the steps of determining the sunset and sunrise times for the day and determining whether the present time is between sunrise and sunset or between sunset and sunrise. The backlight may be driven at a daytime level if the present time is between sunrise and sunset, while the backlight may be driven at a nighttime level if the present time is between sunset and sunrise. In some embodiments, artificial ambient sensor (AAS) data is used to determine the desired backlight or display luminance. The AAS data may be adjusted for a sunset or sunrise transition time, as well as for an approximate percentage of cloud cover in the sky.
